Bumper to Bumper Radio, the car guys on KTAR, 92.3 FM in Phoenix, AZ, broadcast every Saturday from 11:00 am to noon. On this show, Dave Riccio of Tri-City Transmission in Tempe, AZ and Matt Allen of Virginia Auto Service in Phoenix, AZ talk about the frustration that comes with being unable to replicate a car problem once you’re at your auto repair shop.

• Why your personal driving habits can contribute to issues that your auto repair shop can’t find.
• Which intermittent issues are important to fix immediately, and which can just be annoying to the driver.
• How an “event log” can be helpful to diagnose a problem with your vehicle and which factors you should be keeping track of.
• How a weak battery can be contributing to a number of intermittent issues.
• 2014 Chevrolet Silverado: Around 5 times a week, my truck is revving high between second and third gear. How can I have this intermittent transmission issue properly diagnosed?
• 2001 Nissan Altima: My car seems to be losing power at a stop, unless the AC is off. Have you seen this problem before?
• 2005 Jeep Wrangler: I had my transmission rebuilt 15k miles ago, along with my O2 sensors. Since then, I’ve had issues with them. Is there another part that could be contributing to this?
• 2014 Honda CRV: I’m having a hard time opening the hatch on my vehicle, especially when it’s cold. How can I fix this issue?
• 1994 Mercury Cougar: This vehicle has been overheating for some time. One shop has told me to never add water to the cooling system. What are your thoughts?
• 2005 Porsche Cayenne: Do you have a shop that you recommend I take my Porsche to for maintenance?
• 1997 Acura CL: How can I properly have my car diagnosed if my ABS light is coming on intermittently?
• 2005 Ford F150: My truck begins to shudder around 40-50 mph. Is this a problem with my sparkplugs?
• 2004 Chevrolet Venture: My van has been overheating, even after replacing the radiator. Could this be related to my air conditioning system?
